Be it known that I, HENRY L. GAN'ijr, 'a'

citizen' of the United` States, residing at H Pawtucket, county-.of Providence, State ofy 'proved `Apparatus for .'.Treating Cloth, 'of

Which the following is a specification.

i It is particularly applicable to the treagtnient of cotton cloths.

The apparatus comprises a vertically vdi's" posed .shaft communicating at` the bottom; with an inclined chamber or chute Whose delivery end is turned orcurved upward and I may be l.parallel with'the feet shaft or in- I v yor entanglement o f the rope. .I am aware y lthat heretofore it has been proposed t9 con clined toward it.: or the chute may be curved or circular .in 'vertical plane. The bottom of 4this chute .is yforxr'ied,.so far as the su port o'f the cloth is concerned, of a series of'treely .revolving rollers that eXtendnpWardIy at both the receiving and -deliveryends of'the chute. The rollers as well as their bearings andjournal's are to be of suitable-materlal v,to resist action of the bath with' which they .arein contact. Theyr are to be independentl" mounted 's'o as to ,individually revolve .free y under stress Aof 'pressure of the cloth.

Cloth introduced into the shaft or piled Itherein is deliveredlto .the receiving end of the chute and, as the ".pile in the shaft increases, the accumulatedcloth will, by gravity, tbe carried around orthrouffh theach'ute.

i t's. 'tra'vel therethrough being facilitated by lthe 'freely'revolving rollers and 4at the place )of delivery-thatend of the .cloth rope first introduced into the stach' willige on-top and .thecloth rope may be'withdrawn freely with- .out tanglin To facilitate'passageof the piled cloth rom the shaft'through vthe chute,

the latteris constructed with a gradually inrcreasing cross section from the receiving to 'thedelivery end thereof. A machine of this character can be constructedto hold any deupon the weight of the cloth, p'eryard, the, speed at which itis moved in rope f orm, and the time it is to be subjected to-,the action of the solution while piled' down in the ch'ute.- If the clothrope is caused to travel atthe rate of vt'wo hundred yards per minute and it is desired tc keep. it piled down thirty minutes, the machine should bejof capacity @ahold .fortr'eatmee 'the chjaitefsiir tix-duf sand yards vand the size of thechite willdepend upon the weight per lyardtif the cloth.` The chute may -be watertight and if so any vdesired solution may be caused vto continuously circulatetherein. Thecloth rope may be continuously piled down inthe stack and continuously Withdrawn from the deliveryY f end, Every portion of the cloth in this con- .65 tinuous treatment will receivethe same ac-v tion or be-subJected .1n the same manner 'and-f' v 'for the same length of time to fthe solution circulated in the'chute.

Practical experience has` demonstrated that 'a machine constructed in accordance with the foregoing general description has' a hi' h el'liciency land permits the continuous. 1

han ing of cloth rope in the manner de# scribed without; interruption of the process struct an' apparatus designed for the same i. general-purpose with a feeding shaft, la 've'rtical curved circular chute, the bottom 'of 80' which is formed by an endless power driven slatted beltfbut I vhave determined by ex# perience that such an apparatusi's inca able? f of handling cloth in the ractical, satlsfa'e- V tory andeflicient manner 1n which' it. may-be 85 handled with the apparatus disclosed herein.

' In the accompanying drawings; Figure "1 j is 'a vertical longitudinal section through one v form of the apparatus; Fic. 2, a horizontal section on the line 2,*2, cf ig. l; Fig. 3; a 90 vertical longitudinalI section throughv an'- other'formof the apparatus; Fig. 4,atransverse section therethrough on' the line 4, 4, of Fig. 3; and Fig.' 5, a transverse section Lon the line 5, 5, of F ig'. 3: 95

The feed shaft Alofjany appropriate constructlon, is -vertically disposed and o f a height suitable for vthe quantity or lweight f OfA cloth that is to travel through the chute` In -Fig-1, .the chute B is curved in vertical plane and may be square or rectangularin 'cross' section. Its cross sectional' area'. in' creasesjfromfthe lentrance or feed endb Ito the-delivery or-exit end c.' The loottorm'', oif'44r` the chute overl which the :cloth- .travelsjfs 10'5 formed by a .se-ries of transversely arranged' '1 freely 'revolving rollers Dj whse,journals" are mounted in suitable bearingr blocksd as indicated in Fig. 5, This series" of .closely placed independently revolvinv'ro'llers 1s 110- carried well up towards the shafl at th-feed j end and also toward the delivery `md'of the.

chute, the design being that the rollers slmly be s placed that the gravity thrust of the cloth piled flown in the stack shall be faeili lated in causing the passage of the pile through the chute from the feecl end to the delivery end where the end of the cloth reps iii-st intioducecl to the stack will be on top. The apparatus may he constructed of tim bei'. The rollers may he of Wood or Sonie suitable composition. lt is entirely feasible that thelmllers, their journals and the jour nal boxes he all constructed of wood.

ln Figs. 3 anal 4, the construction is p'actically the same except that the chute instead of being curved or ciiculai" in vertical plane is curved at the i'eceiving end; then inclined; and, towards the delivery end. curved upwardly and inwardly so that the central axis of 4the delivery opening, if prelongechwould intersect a line passing through the axis ol. the stach'. The purpose of Such inclination ot' the, delivery enel of the chute is to cause the piled fabric as it ises t0 fall inwardly toward the Shaft. and thereby facilitate the continuous withdrawal of "he cloth i'ope. When the apparatus is se consti` etal, l prelei that the inner eueveel wall of "his poi-tion of the chute be also supplies?. with. s;- Seiies of rolles lf the casing foimiug oi? incles chute he wauw-tight it may have a. en )pl'jpipe E ariel. e. disehaige-pspe l? for encule 'tion of a solution.

'ilhe sides of the shalt A may be formeel Wlmlly'ei pai'tly of vertical. slats with intervening' spaces as shown in the drawings.
